Title: Gyroscopic image motion compensator for a motion picture camera
IPC: G03B19/18
Filed: 1973-01-25
Abstract: In a motion picture camera having a variable focal length lens system including a focal converter and a film exposure window formed therein, behind which film to be exposed passes, an image-movement compensation device is provided for improving the definition of images recorded by the camera when the camera is subjected to vibrations. The image movement compensation device includes a reflecting element mounted in the camera to reflect a collimated light beam from the focal converter to the film passing the exposure window. The reflecting element is mounted for pivotal movement in the camera at the point of incidence of the light beam therewith in the elevation and azimuth planes.

Title: Copy sheet peeler bar having fluid jet assist
IPC: G03G15/14
Filed: 1976-01-21
Abstract: A xerographic copying apparatus having a hot roll fuser and a peeler bar which includes a fluid jet to assist in stripping the toned copy sheet from the hot roll. The peeler bar and jet geometry cooperate with the fusing nip to create aerodynamic forces which tend to peel the sheet's leading edge from the hot roll. This force producing means includes an air jet. The air jet produces pressure differentials to initially pick and guide the sheet's leading edge from the hot roll. The combination of these pressure differentials and the peeler bar's guide surface, positioned to one side of the sheet's path downstream of the hot roll, provides an unconfined and sole support guidance means for the sheet as it leaves the hot roll.

Patent ES-484891-A1 (ES)
Title: A Method and Apparatus for Producing Stranded Wire
IPC: D07B7/02
Filed: 1979-10-10
Abstract: To increase the filling factor of stranded wire, there is provided a frame (1) of a pressing tool comprising a set of rolling rolls (8) through which the stranded wire (17) is drawn. As a result of a decrease in sliding friction between rolls (8) and the stranded wire (17), the inwardly-directed component of compression force acting on the stranded wire (17) is large compared to the rearwardly- directed component of the compression force acting thereon. Hence, there is a greater increase in the filling factor than would be obtainable without the use of rolls. To achieve a more uniform compression of the stranded wire (17), the frame (1) may be provided with a second pressing tool comprising a set of rolling rolls (6) angularly offset relative to the first pair of rolling rolls.

Filed: 1979-11-23
Abstract: A respiration monitor and x-ray trigger apparatus, wherein analog respiration signals (198) are amplified and divided (200) into respiratory and heartbeat components. The analog respiratory components are processed (300), digitized and further processed to yield indications of respiratory extrema (400) and respiration rate (600). The analog heartbeat components are processed (800) to give indications of heartbeat rate (900).

The value of the respiration signal at a sample occurring just after detection of the selected extrema is stored, and modified. Apnea alarms are generated (1000) if a predetermined decrease in respiration rate is detected in successive periods in conjunction with a predetermined number of decelerating heart beats. An alarm is also generated (1100) if the that respiration and heart rates are equal for a predetermined number of periods of if the respiration or heart rates stray outside of preset threshold values.
